YAHOO
Launched in 1994, Yahoo is
the web's oldest "directory," a place where human
editors organize web sites into categories. However, in
October 2002, Yahoo made a giant shift to crawler-based
listings for its main results. These came from Google
until February 2004. Now, Yahoo uses its own search
technology. Yahoo! is one of the best known and most
popular Internet portals. Yahoo is a search engine,
subject directory, and web portal. Yahoo provides good
search results powered by their own search engine
database, and includes cached copies of search results,
much like Google. It was originally a directory on
various subjects and hence it continues to hold
substantial content in its directory that can be
searched directly or browsed by categories. It's also
possible to do a pure search of just the human-compiled
Yahoo Directory, which is how the old or "classic" Yahoo
used to work. To do this, the user must search from the
Yahoo Directory home page, as opposed to the regular
Yahoo.com home page. Yahoo! provide essential consumer
services to increase the value of the overall online
user experience on Yahoo!. These services include:
*
Internet content from over 2000 top-of-the-industry
providers in areas such as news, travel, sports, games,
and weather
*
Commerce services such as shopping, auctions, finance,
and classifieds that enable merchants, enterprises and
individuals to find their audience and complete
transactions efficiently on a worldwide basis
*
Communications services such as Mail, Messenger, Photos,
Greetings, Clubs, and Groups which make communicating on
the Internet, from a PC or wireless device, easier than
ever
*
Yahoo! Everywhere provides consumers with seamless
mobile access to essential, personalized, local and
timely information across a multitude of devices
including wireless phones, two-way pagers and Personal
Digital Assistants (PDAs).
These services make Yahoo! very special to internet
users. The main weaknesses of this site are that there
is a heavy commercial emphasis, some content is dated
and the search results try to keep the users on Yahoo!
Properties. Yahoo! uses Boolean AND by default,
sometimes. For others searches it may do an OR. It uses
what it calls its "intelligent default," but Yahoo! does
not document exactly how that works. So, the results can
vary. Yahoo! does not support Boolean operators or
nested searching. It does support use of the + to
require a term and a - to exclude hits with that term.
Phrase searching is available by using double quotes
around a phrase. To truncate a search term of one to
five characters, the asterisk may be used. Yahoo! has no
case sensitive searching. By using the advanced search
option, the user can limit to just Yahoo! directory
categories or Yahoo! directory sites. One can also limit
to entries added within one of the following specified
periods of time: Anytime, 3 months. 6 months and 1 year.
Like Google, some common words are ignored by Yahoo!
Yahoo! Search Tips
Some search tips that can be followed which using Yahoo!
are: Be concise. As Yahoo’s results are both from a
human edited directory and its own search engine, the
results may not be as targeted as you might like them to
be. Narrowing down your search to a few specific
keywords will help. It is best to use Yahoo keywords.
The user can use field searching in Yahoo's Advanced
Search section.
